Introduction. Modern high-gradient magnetic separation (HGMS) initially originated from a magnetic filter patented in 1937 by Frantz [1], in which the ferromagnetic matrix of fine wires or rods was first introduced into a uniform magnetic field to increase the magnetic field gradient by several orders of magnitude [2].

As shown in Eq. (6) the magnetic force on a weakly magnetic particle is proportional to the magnitude of magnetic flux density and the gradient. So we can get higher magnetic separation performance by increasing the magnetic field and the gradient. The magnetic field can be increased by using a stronger magnet having more …
